Abstract

A system and method are provided for executing an executable clinical practice guideline for providing guidance in treating a patient. A guideline repository stores a plurality of executable clinical practice guidelines. At least one interface receives clinical context data associated with at least one of the patient and the patient'"'"'s treatment. A system server, upon receipt of said clinical context data, automatically chooses an appropriate guideline and controls a display to display the guideline at its present level of abstraction, and a visual navigator which defines the current level of abstraction. The level of abstraction is changed via a user input between a higher level of abstraction in which fewer more abstract steps of the guidelines are displayed and a lower level of abstraction in which more, detailed steps are displayed.

a user input device by which a user changes the displayed guideline resulting in a new guideline being displayed at a new level of abstraction and the visual navigator displaying the new level of abstraction, such that the level of abstraction is changeable by the user input in both a manual mode and an automatic mode.

2. The computing system as set forth in claim 1, wherein the practice or professional guideline includes a clinical practice guideline developed based on medical literature and defining a role of specific diagnostic and therapeutic modalities, including non-invasive and invasive procedures, diagnosis, and management of patients with various diseases, the clinical practice guidelines describing a range of generally acceptable approaches for diagnosis, management, and prevention of specific diseases or symptoms.

3. The computing system as set forth in claim 2, further comprising:

at least one data source which provides patient data, selected patient data being retrieved from the at least one data source during execution of the retrieved guideline.

4. The computing system a set forth in claim 3, wherein the at least one server:

determines if the selected patient data to be retrieved from the at least one data source are available;

provides a notification upon an availability of new patient data via the at least one data source; and

when the new data are usable for the selected patient data that was determined to be not available, provides for processing the new patient data including providing for using the new patient data for providing the selected patient data that was not available for use in executing the displayed guideline.

5. A non-transitory computer readable medium carrying a program which when executed controls a processor to perform the steps of:

selecting a clinical practice guideline developed based on medical literature and defining a role of specific diagnostic and therapeutic modalities, including non-invasive and invasive procedures, diagnosis, and management of patients with various diseases, the clinical practice guidelines describing a range of generally acceptable approaches for diagnosis, management, and prevention of specific diseases or symptoms, the selected clinical practice guidelines being selected from among a plurality of clinical practice guidelines stored in a database in response to receipt of at least one of (1) data defining a context of a task at hand and a user'"'"'s manual selection via a user interface (UI);

controlling a display to display the selected clinical practice guideline for user review, a visual navigator which includes a list of available levels of abstraction of the selected clinical practice guideline, and an indication of which of the available levels of abstraction is being displayed; and

in response to a user input, selecting a different level of abstraction from the list of available levels of abstraction via the user interface to change a current level of abstraction of the displayed clinical practice guideline.

6. The computer readable medium as set forth in claim 5, wherein the data defining the context of the task at hand is medical, the context concerns a medical patient, and the guidelines are clinical practice guidelines.

7. The computer readable medium as set forth in claim 5, wherein the context is provided automatically to select the practice guideline.

8. The computer readable medium as set forth in claim 5, further including:

interacting with the list of available levels of abstraction of the displayed navigator to change from the current level of abstraction to a different level of abstraction.

9. A computer based clinical decision support system comprising:
